The Observations
Do not be misled by the term perfect PageRank, It just denotes a PageRank above 4, that’s all. According to the results by research Division with the help of data by SEOmoz, the minimum page rank for all the websites never went below 4, so If you have a PageRank of 4 or more, you stand a fighting chance.

However, a PageRank inculcates a lower responsibility in the overall progress of the website in the ranking ladder. According to the pie chart, just a percent of websites have a PageRank of 10. But one must also keep in mind, that just a percent of websites have a PageRank of 4 (i.e. the minimum).

The Concept
The Gaussian curve in the Graph clearly depicts that higher number of websites have a PageRank of near 8. Not only does the curve depicts lowest number of websites at the ends, but also shows clearly high concavity until a PageRank of 6. This again shows that you have a high chance after a PageRank of 6. The high PageRankers like, addthis or Twitter are exceptions and are beyond the topic of discussions. Think of twitter as a blog (Of course it is a micro Blogging site), but think of it as a guest blog, where you are the guest bloggers, you create unique and original content in just 140 characters, Think of what such content will do when millions of people do the same in just a minute.
For websites with PageRank of 8 Or more, webmasters need not worry, because the P.I.E. Triad seems to suffer a form of inversion and the importance of Internal and External Links are reduced to nil. Which means It is at that Precise point where your Internal and External Links do not matter anymore. This is because the PageRank is already based on algorithm that takes into account, your Link quantity and quality. In other words, Google is giving you a thumbs-up that your content and content linking practices are good enough and you need not work on it anymore.
Conclusions
So, one thing that you must keep in mind is that if you have a PageRank of 4, you still have a chance if you can improve your internal and External Links. People owning a website with PageRank of equal to or more than 8, need not worry because that is when the P.I.E. Triad suffers an inversion. A good number and quality of Links is essential for best site building practices as those are the parameters which enjoy importance over PageRank below 8. So Don’t just focus on PageRank but also on the amount of quality linking.
